孕产妇围生期静脉血栓栓塞风险评估量表编制及信效度检验

Development,reliability and validity of the perinatal venous thromboembolism risk assessment scale for pregnant women

目的编制符合我国国情的孕产妇围生期静脉血栓栓塞风险评估量表并检验其信效度,为临床评估提供工具。方法参考Caprini血栓评估模型及2015年英国皇家妇产科医师协会提出的静脉血栓栓塞指南,辅以相关文献检索并结合临床实际工作需求和研究小组的讨论,对量表条目进行筛选,最终通过专家函询对量表条目进行修订补充,形成我国孕产妇围生期静脉血栓栓塞风险评估量表。采取便利抽样法选取2020年12月至2022年12月于连云港市东海县人民医院和连云港市妇幼保健院诊断为围生期静脉血栓形成的124例孕产妇为调查对象,对量表信效度进行检验。结果共提取5个公因子,累积方差贡献率为51.304%。验证性因子分析结果χ^(2)/df=1.511,RMSEA=0.029,CFI=0.943,TLI=0.942,适配度良好。最终编制成包括有孕产妇个人信息、孕产妇病史、孕产妇妊娠期相关疾病史、孕产妇妊娠及分娩相关信息、孕产妇分娩后相关疾病信息5个维度、27个条目的量表。量表Cronbach’sα系数为0.841,折半信度为0.864,内容效度指数为0.952,条目内容效度指数为0.814~1.000。结论孕产妇围生期静脉血栓栓塞风险评估量表信效度良好,可用以评估我国孕产妇静脉血栓栓塞风险。

Objective To develop a perinatal venous thromboembolism(VTE)risk assessment scale suitable for Chinese pregnant women,and to test its reliability and validity,so as to provide a tool for clinical assessment.Methods The Caprini Risk Assessment Model and the guideline for VTE proposed by the Royal Society of Obstetricians and Gynecologists in 2015 were used as reference.Supplemented by relevant literature retrieval and combined with the actual clinical work needs and group discussion,the scale items were screened.Finally,the scale items were revised and supplemented through expert consultation,and the Perinatal VTE Risk Assessment Scale for Chinese pregnant women was developed.A total of 124 pregnant women diagnosed with perinatal VTE in Donghai County People's Hospital of Lianyungang and Lianyungang Maternal and Child Health Hospital from December 2020 to December 2022 were selected by convenient sampling method,and the reliability and validity of the scale were tested.Results Five common factors were extracted,and the cumulative variance contribution rate was 51.304%.The results of confirmatory factor analysis showed thatχ^(2)/df=1.511,RMSEA=0029,CFI=0.943,TLI=0.942,and the fitness was good.Finally,it was compiled into a scale with 5 dimensions and 27 items,including maternal personal information,medical history,pregnancy-related diseases history,pregnancy and delivery-related information,and maternal post-delivery related diseases information.The Cronbach'sαcoefficient of the scale was 0.841,the split-half reliability was 0.864,the content validity index was 0.952,and the item content validity index was 0.814-1000.Conclusions The Perinatal VTE Risk Assessment Scale for Chinese Pregnant Women has good reliability and validity,which can be used to assess the risk of VTE among Chinese pregnant women.
